POWER WINDOW CONTROL SYSTEM All Power Window Up Functions do not Operate with Entry Lock Switch

DESCRIPTION

When an entry lock switch is pressed and held for approximately 3 seconds: 1) the certification ECU (smart key ECU assembly) receives a switch signal, 2) the certification ECU (smart key ECU assembly) transmits a signal to all the power window regulator motors by multiplex communication via the multiplex network master switch assembly, and 3) all the power window regulator motors are operated to close the windows.
